Abstract
A kind of Invasive lumbar fusion device die trial, belongs to technical field of medical instruments.Comprise straight hand lever, conductive bar, die trial head, it is characterized in that being provided with in the middle of straight hand lever one and can draw and screw out to become with straight hand lever ± auxiliary horizontal the handle at 90 ° of angles, straight hand lever and assist horizontal handle to be provided with to make auxiliary horizontal handle draw the positioner after screwing out and resetting; Die trial head head end rectangularity, initial two broad side surfaces inserting contact vertebral body are in the arc-shaped, the inclined-plane of die trial head cornerwise two jiaos or one-tenth axle center, corner symmetry.Its structure of strutting lumbar portion of this utility model not only easily struts intervertebral space, and structure is simple; Handle not easily keeps off the sight line of operative doctor, brings convenience to operation; Die trial, when armrest handle is difficult to strut lumbar vertebra, can be carried out knocking reinforcing by sliding hammer.In a word, it can save apparatus cost, shortens the time of operation, facilitates performing a surgical operation of operative doctor.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of Invasive lumbar fusion device die trial.
Background technology
Interbody fusion art proposes the earliest and domestic application lumbar intervertebral fusion the most widely.Need the gap intervertebral process of sick vertebra being completed rear distraction vertebral body in operation process, and the fusion device implanting dimension is to reach the normal physiological curvature of human body.If intervertebral space is greater than the fusion device height of implantation.The risk of fusion device slippage may be there is.So must first with die trial determination intervertebral space before implanting fusion device, and intervertebral space can be subject to very large resistance when die trial is implanted when also not strutting, existing die trial needs to coordinate the apparatus as T-shaped fast catcher and so on to insert, or the die trial being fixed with T-shaped handle is inserted, the former adds cost and the complexity of operating theater instruments virtually; In addition, T-shaped fast connecting handle easily keeps off the sight line of operative doctor, makes troubles to operation; And the die trial coordinating the die trial of the apparatus of T-shaped fast catcher and so on or be fixed with T-shaped handle is inserted when being also difficult to insert just very difficult to die trial force in addition; Also having existing die trial to strut the complex structure of lumbar portion, all there is above-mentioned fraud in the prior art as notification number CN 202355456 U " a kind of lumbar spondylolisthesis intervertebral pulling positor ", notification number CN 201847760 U " vertebral column centrum expanding device " etc.
Summary of the invention
For the above-mentioned disadvantage that prior art exists, the purpose of this utility model to provide a kind of Invasive lumbar fusion device die trial, and the structure that it struts lumbar portion not only easily struts intervertebral space, and structure is simple; Handle not easily keeps off the sight line of operative doctor, brings convenience to operation; Die trial, when armrest handle is difficult to strut lumbar vertebra, can be carried out knocking reinforcing by sliding hammer.
Above-mentioned goal of the invention is achieved through the following technical solutions a kind of Invasive lumbar fusion device die trial, comprise straight hand lever, conductive bar, die trial head, its main points are to be provided with in the middle of straight hand lever one and can draw and screw out to become with straight hand lever ± auxiliary horizontal the handle at 90 ° of angles, straight hand lever and assist horizontal handle to be provided with to make auxiliary horizontal handle draw the positioner after screwing out and resetting; Die trial head head end rectangularity, initial two broad side surfaces inserting contact vertebral body are in the arc-shaped, the inclined-plane of die trial head cornerwise two jiaos or one-tenth axle center, corner symmetry.
As preferably, straight hand lever afterbody is provided with sliding hammer mount pad, and a sliding hammer is detachably movably arranged on sliding hammer mount pad.
As preferably, described sliding hammer by the striking head being arranged on mounting head on sliding hammer mount pad, mobile jib upper end by it of mobile jib, mobile jib lower end, the handgrip composition in the middle part of mobile jib.
As preferably, described positioner is on straight hand lever, be provided with locating hole or location collision bead, and auxiliary horizontal handle is provided with corresponding location collision bead or locating hole; Described straight hand lever is cylindrical.
The beneficial effects of the utility model: it struts the structure of lumbar portion: two broad side surfaces of initial insertion contact vertebral body are in the arc-shaped, the inclined-plane of die trial head cornerwise two jiaos or one-tenth axle center, corner symmetry, so it easily struts intervertebral space after inserting lumbar vertebra, and structure is simple; Handle by straight hand lever with can draw screw out to become with straight hand lever ± the auxiliary horizontal handle at 90 ° of angles forms, and based on straight hand lever use, even if auxiliary horizontal handle draws back-out to be also 1/2nd of existing T-handle, so not easily keep off the sight line of operative doctor, bring convenience to operation; Die trial, when armrest handle is difficult to strut lumbar vertebra, can be carried out knocking reinforcing by sliding hammer.In a word, this utility model can save apparatus cost, shortens the time of operation, facilitates performing a surgical operation of operative doctor.
